Wulftec LMB-250 Lumber Strapping System

Hydraulic Compression Strapping System Designed for Lumber

The LMB-250 Lumber Press is specifically designed for the lumber and panel industries. The hydraulic compression strapping system design facilitates maintenance and operation. Top and side compression ensures stable, tight loads that will retain high tension during transportation. The LMB-250 Lumber Press is easily integrated into existing production lines to create a seamless packaging system.


  • AC variable frequency drives are standard equipment on all machines
  • Lower maintenance and better reliability
  • Wulftec stretch wrappers will save time and money
  • NEMA 4/12 control panel dust tight and waterproof
  • Control panel is neatly organized eliminating time otherwise lost searching for wires<
  • Control panel is UL508A approved
  • Superior electrical design including Allen Bradley MicroLogix PLC and AC drives
  • User-friendly touch-screen offers a simple yet effective way to adjust and maintain your equipment
  • All motors, proximity sensors, photoeyes and other sensors have quick disconnect cables that simplify installation and maintenance
  • Photoeyes are maintenance free and protected
  • All Wulftec structures are made of heavy-duty steel for rugged performance, even in the harshest work environments
  • Wulftec machines are built to last forever
  • During the strapping cycle, the strapping head indexes towards the load before tensioning sequence, so tensioning and sealing are done against the side of the load.
  • The strapping head is mounted on a movable assembly guided through linear bearings, and activated by an electric motor with a timing belt. The head has a load sensing device that detects the side of the load and tells the head movement to stop so tensioning and welding are done as close as possible to the product for maximum strap containment efficiency.
  • The bottom section of the strapping arch can be a standard undertrack style or an electric motor driven pallet bayonet for "through-pallet" strapping or a combination of both.
  • Up to 8 straps per minute may be applied, depending on strapping arch and package dimensions, strap quality and strap tension required. PET or polypropylene strap may be used with minor adjustments to the strapping head.
  • Electronic tension control through a variable frequency drive. Assures consistent tension control regardless of the number of cycles and environmental conditions. The strap tension is adjustable from the touch screen.
  • Wulftec heavy-duty conveyors are second-to-none in the industry
  • Coils of PET or polypropylene strapping with a core diameter of 16" can be fitted to the high speed dispensers, with pulley block accumulation system and electrical brake.
  • Ability to strap with polyester or polypropylene strapping without parts changes.
  • Non-Proprietary parts accessible on a local base
